BCM5670 8-PORT, 160 Gbps SWITCH FABRIC
FEATURES
SUMMARY OF BENEFITS
⢠Eight 10-Gbps (HiGigâ¢) switch fabric ports
⢠Nonblocking, 160-Gbps wire speed, backplane/switch fabric
performance
⢠Forwarding rate of 119 million packets/second
⢠Eight Integrated high-speed XAUI interfaces
⢠Eight programmable priority queues per port
⢠Port trunking and mirroring across multiple devices
⢠Hot-swap capable with AC coupling
⢠Supports redundancy on linecards for chassis-based
applications
⢠Advanced diagnostic features including IEEE 1149.1 boundary
scan, JTAG and extensive BIST functionality
⢠Resilient link configuration through active multipath
forwarding
⢠PCI interface
⢠I2C interface
⢠Broadcom switch API compatibility
⢠Advanced 0.13 µm CMOS technology
⢠Small 600-pin EBGA package
⢠Low power: 10W
⢠System vendors can build high-performance, high-density
Gigabit Ethernet LAN switches in several form factors.
⢠Support for multiple CoS and very low latency enables the
support of VoIP and other voice, video, and data applications.
⢠Built-in high-speed XAUI interfaces with Broadcom-unique
SerDes technology eases and accelerates system design, while
reducing cost and conserving board space.
⢠A 1152-KB internal data buffer memory eliminates the need
for expensive external memory.
⢠Drives up to 10m of low-cost copper cables for stacking switch
applications.
⢠Broadcom switch API compatibility enables reuse of resources
and fast time-to-market.
TARGET APPLICATIONS
⢠Switch fabric in modular Gigabit Ethernet switches
⢠Switch fabric in high-port-count stand-alone or stackable
Gigabit Ethernet switches
⢠Switch fabric for chassis and in-server switch blade
applications
